cefd0302b5 evaluate inherit (from) exprs only once per directive
desugaring inherit-from to syntactic duplication of the source expr also
duplicates side effects of the source expr (such as trace calls) and
expensive computations (such as derivationStrict).

nix profile: suggest removal using entry name
When a file conflict arises during a package install a suggestion is
made to remove the old entry. This was previously done using the
installable URLs of the old entry. These URLs are quite verbose and
often do not equal the URL of the existing entry.

This change uses the recently introduced profile entry name for the
suggestion, resulting in a simpler output.

The improvement is easily seen in the change to the functional test.

efd36b49e8 nix hash path, and preperatory refactors
- `nix store add` supports text hashing

  With functional test ensuring it matches `builtins.toFile`.

- Factored-out flags for both commands

- Move all common reusable flags to `libcmd`

  - They are not part of the *definition* of the CLI infra, just a usag
    of it.

  - The `libstore` flag couldn't go in `args.hh` in libutil anyways,
    would be awkward for it to live alone

- Shuffle around `Cmd*` hierarchy so flags for deprecated commands don't
  end up on the new ones

071dd2b3a4 Input: Replace 'locked' bool by isLocked() method
It's better to just check whether the input has all the attributes
needed to consider itself locked (e.g. whether a Git input has an
'rev' attribute).

Also, the 'locked' field was actually incorrect for Git inputs: it
would be set to true even for dirty worktrees. As a result, we got
away with using fetchTree() internally even though fetchTree()
requires a locked input in pure mode. In particular, this allowed
'--override-input' to work by accident.

The fix is to pass a set of "overrides" to call-flake.nix for all the
unlocked inputs (i.e. the top-level flake and any --override-inputs).

0acd783190 Don't send settings that depend on disabled experimental features to the daemon
This fixes warnings like

   warning: Ignoring setting 'auto-allocate-uids' because experimental feature 'auto-allocate-uids' is not enabled
   warning: Ignoring setting 'impure-env' because experimental feature 'configurable-impure-env' is not enabled

when using the daemon and the user didn't actually set those settings.

Note: this also hides those settings from `nix config show`, but that
seems a good thing.

319ec6f84a Support Windows paths in canonPath and absPath
`canonPath` and `absPath` work on native paths, and so should switch
between supporting Unix paths and Windows paths accordingly.

The templating is because `CanonPath`, which shares the implementation,
should always be Unix style. It is the pure "nix-native" path type for
virtual file operations --- it is part of Nix's "business logic", and
should not vary with the host OS accordingly.

d17e1d9737 Purify CanonPath
The core `CanonPath` constructors were using `absPath`, but `absPath` in
some situations does IO which is not appropriate. It turns out that
these constructors avoided those situations, and thus were pure, but it
was far from obvious this was the case.

To remedy the situation, abstract the core algorithm from `canonPath` to
use separately in `CanonPath` without any IO. No we know by-construction
that those constructors are pure.

That leaves `CanonPath::fromCWD` as the only operation which uses IO /
is impure. Add docs on it, and `CanonPath` as a whole, explaining the
situation.

This is also necessary to support Windows paths on windows without
messing up `CanonPath`. But, I think it is good even without that.

Restore builtins.pathExists behavior on broken symlinks
Commit 83c067c0fa changed `builtins.pathExists`
to resolve symlinks before checking for existence. Consequently, if the path
refers to a symlink itself, existence of the target of the symlink (instead of
the symlink itself) was checked. Restore the previous behavior by skipping
symlink resolution in the last component.

41dd9857c7 Proper parse and render functions for FileIngestionMethod and ContentAddressMethod
No outward facing behavior is changed.

Older methods with same names that operate on on method + algo pair (for
old-style `<method>:algo`) are renamed to `*WithAlgo`.)

The functions are unit-tested in the same way the names for the hash
algorithms are tested.

ecf8b12d60 group inherit by source during Expr::show
for plain inherits this is really just a stylistic choice, but for
inherit-from it actually fixes an exponential size increase problem
during expr printing (as may happen during assertion failure reporting,
on during duplicate attr detection in the parser)

6c08fba533 use the same bindings print for ExprAttrs and ExprLet
this also has the effect of sorting let bindings lexicographically
rather than by symbol creation order as was previously done, giving a
better canonicalization in the process.

Rename hintfmt to HintFmt 2024-02-08 11:58:25 -08:00

149bd63afb
Cleanup fmt.hh
When I started contributing to Nix, I found the mix of definitions and
names in `fmt.hh` to be rather confusing, especially the small
difference between `hintfmt` and `hintformat`. I've renamed many classes
and added documentation to most definitions.

- `formatHelper` is no longer exported.
- `fmt`'s documentation is now with `fmt` rather than (misleadingly)
  above `formatHelper`.
- `yellowtxt` is renamed to `Magenta`.

  `yellowtxt` wraps its value with `ANSI_WARNING`, but `ANSI_WARNING`
  has been equal to `ANSI_MAGENTA` for a long time. Now the name is
  updated.
- `normaltxt` is renamed to `Uncolored`.
- `hintfmt` has been merged into `hintformat` as extra constructor
  functions.
- `hintformat` has been renamed to `hintfmt`.
- The single-argument `hintformat(std::string)` constructor has been
  renamed to a static member `hintformat::interpolate` to avoid pitfalls
  with using user-generated strings as format strings.

Pretty-print values in the REPL
Pretty-print values in the REPL by printing each item in a list or
attrset on a separate line. When possible, single-item lists and
attrsets are printed on one line, as long as they don't contain a nested
list, attrset, or thunk.

Before:
```
{ attrs = { a = { b = { c = { }; }; }; }; list = [ 1 ]; list' = [ 1 2 3 ]; }
```

After:
```
{
  attrs = {
    a = {
      b = {
        c = { };
      };
    };
  };
  list = [ 1 ];
  list' = [
    1
    2
    3
  ];
}

print-dev-env: Avoid using unbound shellHook variable
Some tools which consume the "nix print-dev-env" rc script (such as
"nix-direnv") are sensitive to the use of unbound variables. They use
"set -u".

The "nix print-dev-env" rc script initially unsets "shellHook", then
loads variables from the derivation, and then evaluates "shellHook".
However, most derivations don't have a "shellHook" attribute.

So users get the error "shellHook: unbound variable". This can be
demonstrated with the command:

    nix print-dev-env nixpkgs#hello | bash -u

This commit changes the rc script to provide an empty fallback value
for the "shellHook" variable.

Closes: #7951 #8253
